This is what ASCS had for a rule allowing open heads in the beginning. I think it is time to revisit it or make unaltered heads all together!!
G.4.3 Non spec Chevy heads will be allowed, but must have an unaltered ASCS intake restricting gasket installed. Unaltered means absolutely no modifications to bolt holes or port sizing. These gaskets are to be installed right side up with logo on top. The ASCS restrictor gasket must protrude a minimum of .150 inch into the roof line of both the injector and the cylinder head port. There shall be no streamlining or re-contouring of intake ports or injectors to reduce the effect of the restrictor gasket. Non spec heads must have stock intake bolt location and injector manifold is to be installed with stock 3/8 inch diameter bolts. No step studs or relocating bolts. You CANNOT enlarge or relocate restricting gasket bolt holes. (Note: This rule will be eliminated for the 2008 season, only ASCS heads will be allowed.)No Brodix #12 heads - no 18 degree heads, no canted valve heads, no heads other than original 23 degree valve angle heads. All aluminum heads must remain within 1 degree of the OEM valve angle.G.4.4 All oil pans must have inspection plug. Pans without plug will be subject to pan removal at anytime.

Amen. The 2008 change to only ASCS heads was nothing but a money grab. That wasn't even so bad when they actually teched and kept them realatively in check. Now its just more money grab fo the guys who do the porting. The racing certainly isn't any better than back then. The payouts aren't any better. It just costs more to do it and you never know what your racing against. I've asked this before and no one that really knows ever answers. What affect would the gasket actually have? Would it do what most racers who I know want, that's eliminate the gain of all this porting going on now? And is it pretty easy to tech the gasket without taking it out? If the answers to those two questions are yes then I'd be all for it. I won't hold my breath though. I don't expect anything to help the low budget guys compete.

There are still some hand porters out there but I'd say it's about 90% CNC anymore
